"Using these daily helped my digestion a lot without any undesirable effects." ~ product review by jackalan

  • Alternative to serrapeptidase

  • A proteolytic enzyme

  • Keeps joints comfortable and mobile

Swanson Ultra High Potency Serrazimes is a proteolytic enzyme (a substance that promotes the breakdown of protein) that can support joint, circulatory, respiratory, and immune health. It was designed as an alternative for serrapeptidase, a product initially isolated from a bacteria found in the gut of the Japanese silkworm. Serrazimes has the same fibrinolytic activity in vitro as serrapeptidase supplements.

phony reviews Most of these reviews ( including the #1 reviewer) refer to Serrapeptase as though it was a probiotic. It is not. It digest fibrins in the blood vessels. Serrazimes have nothing to do with one’s digestive system. They help clear your blood vessels. March 12, 2014
Great, exceeded my expectation I notice a pronounced benefit taking this, more so than most supplements. The price was very fair. Glad I tried it. November 12, 2013
serrazimes I found it hard to find a time to take these that are 2 hours before or 2 hours after food, until I started taking them before bedtime. They do a great job of keeping me regular and feeling more energetic. September 9, 2013
different schedule Many reviewers have had a problem with dosage schedule. An answer that worked for me. I put two out before I go to bed and take them when I get up to go during the night. Works for me. August 27, 2013
Wonderful buy!!! It really works for me in combination with Ribose, Malic Acid, Rioobos, and it is a great product August 14, 2013
serrazymes How can you possibly beat the price. Folks - if you don't believe in taking proteolitic enzymes then you should study what they can do for you- that's for anyone over 50 for sure. This price is unbelieveable; certainly the best I could find by far August 2, 2013
EXCITED ABOUT ENZYMES I have always been a big proponent of Enzymes. I know that different enzymes have different functions, and I take a combination of digestive enzymes with meals and supplements to maximize my utilization of nutritional value from those sources. I am very glad to be able to use this Systemic Enzyme, Serrazimes, that benefits my joints, circulatory, respiratory, and immune systems. Systemic Enzymes are so important for life functions throughout the body. I feel that my flexibility / mobility, circulation, breathing, and wellness are all extraordinarily excellent, and all benefit from Serrazimes. It is easy for me to be able to get 2 capsules in at different times on an empty stomach daily. The capsules are a nice small size and user-friendly. I keep the bottle out in plain sight, so I can be sure to grab a capsule on an empty stomach. I want to maximize my benefits from the Serrazimes that way. Out of sight, out of mind, you know. . . . And I do not want to miss out on taking my Serrazimes consistently. I feel that Serrazimes are important to my overall health / fitness / and wellbeing. June 12, 2013
Serrazimes Based on the many reviews of this product I'm certain that many customers find this supplement beneficial. I did not. I experienced nervousness, including shaky, tingly hands which stopped within 12 hours of stopping this supplement. I don't have what could be called a "strong constitution" and I've always been highly reactive to some things I've taken. This seems to be one of them. It might help you, might not. You know your body better than anyone else so this product is recommended with reservation. June 5, 2013
Serrazimes high potency Works better for me than probiotics. One pill works for me. Take on an empty stomach. Will keep using. April 28, 2013
Good supplement Using these daily helped my digestion a lot without any undesirable effects. February 14, 2013
Great Product, Best Price! Defintely works to keep things open and moving. December 18, 2012
Serrazimes This is a product that needs to be taken regularly per the directions. But, if you're someone like me who needs to eat every two to three hours, it is difficult to have an empty stomach for it to work properly. My high metabolism requires constant nourishment. I see this product as very beneficial for others who hardly eat. October 4, 2010
wonderful product I'm very happy and pleased with this product, I take it every day twice a day, I have recommended it to several people and they are all very pleased with it. My brother is the one that recommended it to me and he is still taking it too. May 7, 2010
Same relief for less I was taking 5-6 10mg tablets of serrapeptidase, now I only take 2 capsules a day for the same results. March 15, 2010
Almost Immediate Improvement! After reading reviews of how this helps to minimize mucous, I started taking it. I noticed a much reduced amount the very first night. I didn't wake up needing to blow my nose or w/ back of throat drainage. I slept better and my husband told me my snoring was greatly reduced. I only wish it wasn't nec. to take on an empty stomach twice a day...that's not always so easy. But, the effects are worth it for me. December 31, 2009
Try it, you'll like it We all need a little something to help digest those pesky proteins from time to time. Fibrin got you down? Try this proteolytic enzyme to "digest" your troubles away (take between meals). Very reasonably priced. July 30, 2009
Best source for this product A best buy anywhere for this product at its stated potency. My wife and I and my eldest son (disabled, mid 40's) all take this product and like the way it helps us to feel better. November 13, 2008
Great Product! This is a great product and supplement. I take it daily for the many uses that it is known for. I feel good knowing that taking a supplement like this is actually good for my body! May 2, 2008
This stuff is good. I know we're not supposed to right about conditions, so I'll just say the Serrazimes is my best purchase ever. It's allowed me to get mobile again after many years of ware and tear on my body. July 26, 2007
